Rebar coupler is used to connect the two rebar ends in the construction work. 1. Easy Operation, saving time and rebar material. The rebar coupler producing and rebar end threading will not be affected by the weather; it can be processed before processing. 2. It can connect the rebar with the diameter 14mm to 40mm. 3. Use No.45 steel, with the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part. size16-40mm.
Hbly rebar coupler Specification: -material: 45constructional carbon steel -color: white -package:carton and wooden pallet -with high tensile strength and good quality. Technical date: .The material of the splicing coupler is carbon constructional quality steel of no.45. .The coupler can link the rebar which diameter from 16mm to 40mm .The tensile strength of the coupler can be more than 570 mpa .This kind of connection is more rapid and simple convenient The characteristics of the usage 1.Standard model65306; Used in the occasion for connecting the steel bar in normal situation 2.Different diameter model65306; Used for connecting the steel bar in different diameter 3.Flared model65306; Sed for the steel bar which was hard to match 4.Positive and negative screw thread model65306; Used in the occasion when the steel bar in the two sides both can not be turned but the lengths can be adjusted. 5.Locking nut model： Used when the steel bar can nut be turned, then it truns the splicing coupler to join the steel bar and then lock the splicing coupler with the locking nut. Standard export carton ad pallet
The material of the cold extrusion rebar coupler is no.20 steel. The features of this technology: 1.Strong intensity connector, stable and reliable; no specific requirements on the weld ability of the rebar; 2.Only needs 1-3m to stamp each connector, which is about ten times faster than ordinary welding; 3.Only 1-3 kw power of oil pump , which is not limited by power capacity, has flexible structure and suitable for operation on several machines; Yj650 stamping equipment 4.No flammable gases, not affected by rainy or cold weather; 5.Relieve congestion of the connecting point, facilitated concrete pouring; 6.No professional and experienced worker needed, able to connect changed steel bar of different diameters; 7.Save 80% of connector steel consumption. The technology is assessed by the ministry of construction as "world advanced, high quality, high efficiency, safe, and economical thick diameter distorted steel bar connection technology which can be widely used in the construction industry." Cold extrusion application principle: 1.Place it well at the working point. 2.Directly use it to press connection point with screwless couplers to link the two rebar. -
The material of the splicing coupler is constructional quality steel of no.45 steel. Working principle: 1)slice up the end of the rebar; 2)peel the rib of the end of rebar with specialty rib peeling parallel thread rolling machine; 3)connect the two ends of rebar with rib peeling thread coupler; The characteristics of the usage: 1.Standard model: used in the occasion for connecting the steel bar in normal situation. 2.Different diameter model: used for connecting the steel bar in different diameters. 3.Flared model: used for the steel bar which was hard to match. 4.Positive and negative screw thread model: used in the occasion when the two sides both can not be turned but the lengths can be adjusted. 5.Locking nut model: used when the steel bar can not be turned, then it turns the splicing coupler to join the steel bar and then lock the splicing coupler with the locking nut.
Advantages: Bar-break feature guarantees fully ductile elongation. No reduction of the bar cross-section area. Working principle: 1, first, we use gq50 rebar cutting machine to splice up the end of rebar. 2, secondly, we use upset forging parallel thread machine (bdc-auto1 machine) to forge the end of rebar. 3.Third, we use parallel thread cutting machine (lw-i500 machine) to thread the ends of the rebar which have been forged. 4.Fourth, an upsetting coupler is used to link the two ends of rebar in parallel thread.
